Key Takeaways

  • Defensive Architecture: The Theodosian Walls featured three-layer defense with 8-meter outer wall, 20-meter towers, and 12-meter inner wall creating a kill zone that protected Constantinople from land attacks for 1,000 years until cannon technology emerged.
  • Strategic Diplomacy: Anthemius renewed peace treaties with Sassanid Persia immediately upon taking power, preventing two-front warfare and keeping lucrative Asian trade routes open while focusing military resources on northern Hun threats along the Danube frontier.
  • Political Transition Management: Seven-year-old Emperor Theodosius II's succession in 408 CE proceeded smoothly because Anthemius provided continuity of leadership and policy, demonstrating how competent regents enable stable transfers of power during vulnerable child-emperor periods.
  • Catastrophic Policy Failure: Olympius ordered genocide of Gothic families in Italian cities in 408 CE, immediately driving 12,000 trained Gothic warriors from Roman service to Alaric's army and transforming him from marginalized figure to major military threat overnight.

What It Covers

The Eastern Roman Empire stabilizes under Praetorian Prefect Anthemius after 408 CE through strategic wall construction and Persian diplomacy, while Alaric's Goths blockade Rome three times seeking territorial recognition after anti-barbarian massacres drive warriors to his cause.

Notable Moment

Alaric abandoned demands for independent Gothic state, gold payments, and military commission, requesting only settlement rights along Danube with grain supplies. Honorius inexplicably rejected this favorable deal, forcing Alaric to install rival emperor Priscus Attalus in Rome.

This holiday season, reach for the one butter that never disappoints, Kerrygold. Made with milk from grass fed cows on Irish family farms, it's rich, creamy, and perfect for baking. Whether browning butter for cookies or crafting the flakiest pie crust, Kerrygold's high butter fat content makes all the difference in flavor and texture. Holiday treats will taste extraordinary. Hello, and welcome to the history of Rome, episode one sixty three, Theodosius' walls. We've spent the last two weeks focused primarily on the Western Empire during the first decade of the April. So before we just keep barreling along into the sack of Rome and the fall of Constantine the third, I wanna double back and bring the Eastern Empire up to speed. But, just so you know, as soon as we're caught up, we're going to head right back to the West because, basically, that's where all the action is right now. The thing to understand about the Eastern half of the empire in the years after Theodosius's death is that though the eastern court was far less stable politically than the Stilicho led western court, the Eastern Provinces as a whole were far more stable than the Western Provinces as a whole. The population migrations brought on by the Hunnic advance onto the Hungarian Plain tended to drive displaced local barbarian tribes west rather than south, which meant, as we saw last week, that the Western Provinces wound up dealing with the consequences of those disruptive migrations. On top of that, Sasanid Persia had been peaceful since signing a treaty with Theodosius back in the March, a treaty that Stilicho helped broker. So the Eastern Legions could afford to focus on deflecting those barbarian migrations west instead of allowing them to come south. Indeed, in just a minute, Constantinople and the Sassanids will renew their peaceful terms, and that renewal will further stabilize the Eastern provinces, both because it meant the Romans didn't have to pour resources into fighting the Persians, but also because it meant the lucrative trade routes to and from Asia remained open for business. As we've seen, in the late three nineties and early four hundreds, the emperor Arcadius was dominated by a shifting cast of ministers and generals who focused on winning and holding power at least as much as they focused on actually governing the Eastern Empire. The only permanent political presence during these years was the Empress Eudoxia, whose influence over her husband never wavered while all these ministers rose and fell around her. In fact, the only real challenge to her authority came not from some ambitious prefect or powerful general, but from an incorruptible clergyman who had risen to become Bishop of Constantinople, John Chrysostom, also known as John the Golden Mouth. Though he would never achieve the same sort of political success that Ambrose of Milan had achieved, there were two critical similarities between the two men. First, both were fearless when it came to challenging imperial authority. …
